Clinical TrialIntravenous lidocaine and small-intestinal size, abdominal fluid, and outcome after colic surgery in horses.
Twenty-eight horses with the diagnosis of an intestinal disorder requiring surgical intervention were randomly assigned to lidocaine (n = 13) or saline (control, n = 15) treatment groups. After induction of anesthesia, treated horses received a loading dose of 2% lidocaine (0.65 mg/kg) intravenously, followed by a continuous rate of infusion of 1% lidocaine (0.025 mg/kg/min) until the discontinuation of anesthesia. Upon recovery from anesthesia, a 2nd loading dose of 2% lidocaine (1.3 mg/kg) was administered, followed by an infusion of 1% lidocaine (0.05 mg/kg/min) for 24 hours postoperatively. ⋯ No significant differences between the groups were found in the presence of gastrointestinal sounds, time to passage of 1st feces, number of defecations in the 1st 24 hours, presence of gastric reflux, duodenal or jejunal wall thickness, maximum duodenal or jejunal diameter or cross-sectional area, minimum duodenal diameter or cross-sectional area, duodenal and jejunal intraluminal echogenicity, small-intestinal contractions per minute, rate of complications, or outcome. On the basis of this study, lidocaine infusion may have some desirable effects on jejunal distension and peritoneal fluid accumulation and was well tolerated perioperatively in horses with colic. The low incidence of small-intestinal lesions and gastric reflux in the study makes it difficult to assess the use of lidocaine in the prevention of postoperative ileus (POI).

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of intravenous ketorolac and meperidine in the treatment of biliary colic.
To compare the analgesic efficacy and tolerability of intravenous (IV) ketorolac tromethamine with IV meperidine in the treatment of biliary colic, a prospective, randomized, double blind study was carried out upon a convenience sample of patients at a large inner city facility. Patients between the ages of 18 and 65 years of age with a history and physical examination consistent with biliary colic were enrolled over a 2-year period. Patients were randomly assigned to receive ketorolac 30 mg IV or meperidine 50 mg IV. ⋯ Although no significant difference was found in overall drug tolerability, patients receiving meperidine reported higher incidences of nausea and of dizziness than those receiving ketorolac (p = 0.009 and 0.003, respectively). Ketorolac tromethamine is a well-tolerated, effective medication in the treatment of acute biliary colic. It showed similar efficacy to meperidine with a decreased number of adverse effects.

Review Case Reports
Toothpick injury mimicking renal colic: case report and systematic review.
We describe a case of a patient with left flank pain that was caused by a perforation in the splenic flexure of the colon by a toothpick. We conducted a systematic review of the literature to examine the nature of injuries caused by ingested toothpicks. Articles were analyzed for the following outcome variables: presenting complaint, site of injury, recollection of toothpick ingestion, time to presentation, findings from imaging studies, and mortality. ⋯ The definitive diagnosis was most commonly made at laparotomy (53%), followed by endoscopy (19%). Overall mortality was 18%. Ingested toothpicks may cause significant gastrointestinal injuries, and must be treated with caution.

The differential diagnosis of acute flank pain includes kidney stones, urinary tract infection, dissecting abdominal aortic aneurysm (AAA), arterial or venous compromise of the kidney, renal abscess, renal carcinoma, and papillary necrosis. This is a report of an unusual cause of renal colic: pyelocalyceal diverticulum. Stasis of urine within a diverticulum promotes both calculus formation and urinary tract infection, either of which can lead to colic. Several radiographic findings may suggest a calyceal diverticulum, including, on plain X-ray, a very peripheral or mobile renal calculus, or on intravenous pyelogram, an early filling-defect and delayed or retained filing of a circular or ovoid mass.

To determine the utility of hematuria testing in a large series of patients with suspected renal colic using unenhanced helical computed tomography (CT) as the reference standard. ⋯ The sensitivity of hematuria on microscopic urinalysis for renal colic using unenhanced CT as the reference standard was 84%, and the specificity and negative predictive value was low. The presence or absence of blood on urinalysis cannot be used to reliably determine which patients actually have ureteral stones.
